A sybil farm must front real capital per fake identity, and colluding peers risk slashing. Whispers of new identities spread slowly, like water seeping through karst, so a forged swarm cannot scale before the horizon of the next audit, where unverified keys lose weight and rewards. Cost of attack rises linearly with identity count.
